To all whom t may concern:

Be it known that we, JOHN BODINE FRAZIER and HOMER WICKES, of Oonneautville, Grawtord county, Pennsylvania, have invented a new and Improved Balance Walking-Beam for Boring` Oil-Wells; and we do hereby declare that the following is a full and exact description of the same, reference being had to the aecompanyingdrawingsandletters ofreference I marked thereon.

Figure l represents our invention with all its parts adjusted in working order. Ais the sampson post; B O the Walking-beam, the drill being attached to the end B, and the engine to the end O, in the usual manner. E F is a sand or weight vbox resting,` on the iron bar K K on the end O of the walking-beam. This box is constructed in two parts, E and F, attached together by bars of Wood or metal, as shown at Fig. 2, by 3 4. G is Va strap of wood or metal bolted on the part E of the Weight-box. In the lower part or end of this strap is a slot and key, H, to fasten the weightbox at any desired point on the walking-beam. l and 2 are rollers on which the Weight-box E F hangs, rendering it easily moved or adjusted.

The lower part, F, of the weight-box is hung on the straps 3 4 by a bolt or bolts, 5 6 6 5, Fig. 2. f

Fig. 3 is a sectional view of our invention, showing the key H, the roller 1, the straps 3 and 4, and the parts E and F of the weightbox. l

Our machine works as follows; to Wit: The drill is attached to the end B of the Walkingbeam, and the weight-box E F is lled with the desired amount of sand, and by the mechanical constructions heretofore described is moved and adjusted on the walking-beam so as to balance the drill. By this means great power is saved in operating the drill.
